B&R Industrial Automation X67DM1321 Digital IO Module

The B&R X67DM1321 Digital I/O Module is an eight‑channel block for BR’s X67 I/O system, with each channel configurable in software as an input or an output to suit 24 V DC discrete I/O tasks. It provides channel‑to‑bus isolation up to 500 V (effective) and uses a nominal 24 V DC supply, supporting a combined sensor/actuator current of 0.5 A. The module communicates on the X2X Link bus and uses M12, B‑coded connectivity for the bus, while the eight I/O channels interface via 8 x M8, 3‑pin connectors and a separate 4‑pin M8 power connector for the sensor/actuator supply. Per‑channel LEDs indicate I/O function, supply voltage, and bus status, with built‑in diagnostics to aid fault localization. The X67DM1321 carries the B&R ID code 0x1311 and is CE and UKCA certified. Power consumption is specified as about 2.5 W for internal I/O plus 0.75 W for the X2X Link portion, reflecting a compact footprint suitable for BR control cabinets. This module integrates with BR Automation Studio and BR controllers to enable scalable, software‑driven configuration of digital I/O, making it suitable for reading limit switches and sensors or driving small actuators in 24 V environments.
